我在AT&T汇编语法中为gcc编写了以下代码

.global main
.section .data

to_gen_inner: #x f, implicit n
        pushl %ebp
        movl %esp, %ebp
        movl $0xFF00FF00, %eax
        call printregs
        lret

.set to_gen_inner_len, . - to_gen_inner

.section .text

main:
        pushl %ebp
        movl %esp, %ebp

        #allocate memory
        pushl $to_gen_inner_len
        call malloc
        popl %ecx

        pushl $to_gen_inner_len
        pushl to_gen_inner
        pushl %eax
        call copy_bytes
        popl %eax
        popl %ecx
        popl %ecx

        lcall *(%eax)

        movl %ebp, %esp
        popl %ebp
        ret

printfregs:
        .ascii "eax: %8X\nebx: %8X\necx: %8X\nedx: %8X\n\0"

printregs:
        pushl %edx
        pushl %ecx
        pushl %ebx
        pushl %eax …
